I have heard that H&R make an accurate single shot slug gun. I saw one at Dick's Sporting Goods. It has a real thick barrel, guy said the barrel was a 10 guage barrel drilled to 12guage. It cam with a scope for about 250$. Also comes in 20 guage. I have frieds saw that it was the most accurate slug gun they have used. You will need a sling because it weighs a ton.
